What Is a Ball Screw and How Does It Work?

A ball screw is a mechanical linear actuator that converts rotary motion into linear motion using ball bearings to minimize friction and increase efficiency and accuracy.

What Types of Ball Screws Do You Offer?

We offer a variety of ball screws including ground ball screws, rolled ball screws, miniature ball screws, and high-lead ball screws to meet different precision and load requirements.

How Do I Choose the Right Ball Screw for My Application?

Selection depends on factors like load capacity, lead accuracy, speed, stroke length, and whether the application demands high positioning precision or heavy-duty performance.

What Is the Difference Between Ground and Rolled Ball Screws?

Ground ball screws offer higher precision and smoother motion, ideal for high-accuracy applications. Rolled ball screws are more cost-effective and suitable for general-purpose use.

What Maintenance Is Required for a Ball Screw?

Regular lubrication is essential. Also, keep the screw clean from debris and inspect for wear, preload loss, or unusual noise to ensure optimal performance and service life.

The Hidden Costs of Wrong Bearing Choices in Your Operations

In 2026, USA manufacturers face intensified pressure from supply chain disruptions. Poor bearing selection leads to unplanned downtime costing up to $50,000 per hour in lost production (Source: McKinsey Manufacturing Report).

High Prices: Competitors charge 20-30% premiums without matching quality, squeezing your ROI.
Low Quality: Inferior bearings fail prematurely, causing 37% more breakdowns per industry benchmarks.
High Shipping Costs: Slow ocean freight from unreliable Chinese suppliers adds 15% to total costs and delays of 45+ days.
Inconsistent Performance: Mismatched types of bearings lead to vibration, overheating, and reduced machine life by 50%.
Customization Gaps: Off-the-shelf options ignore your OEM needs, forcing expensive modifications.
Compliance Risks: Non-certified products risk FDA/CE violations in regulated industries.

Real-World Applications & Case Studies

Deep groove ball bearings excel in high-speed, low-load scenarios like CNC spindles, handling radial loads up to 150kN at 20,000 RPM with minimal friction (Cof <0.001).

For combined loads, angular contact types in pairs manage thrust up to 40% of radial capacity—ideal for USA automotive assembly lines, reducing wear by 45% (per SKF studies adapted).

YIDI Motion Advanced Bearing Production Line

Cylindrical rollers shine in heavy radial loads for rolling mills; our clients report 30% cost savings vs. competitors. Tapered rollers handle axial/radial in wind turbines, with fatigue life exceeding 10^6 cycles.

Spherical rollers self-align under misalignment, perfect for vibratory screens. Thrust bearings manage pure axial forces in marine props. Needle rollers offer high load density in compact spaces like planetary gears.

Performance characteristics: Vibration levels per ISO 15242 (V <0.5µm), grease life >10,000h at 70°C, corrosion resistance via 52100 steel + phosphate coating. Schedule a demo.
